SELF-HEATING SMOOTHINGr-IRON.

Specification of Letters Patent No. 14,796, dated May 6, 1856.

To all 'whom t may concern:

Be it known that I, G. IV. BISHUP, of Brooklyn, in the county of Kingsand State of New York, have invented a new and Improved Smoothing or SadIron; and I do hereby declare that the following is a full, clear, andexact description of the same, reference being had to the annexeddrawings, making a part of this specification, in which- Figure l, is aside view of my improvement. Fig. 2, is a longitudinal vertical sect-ionof ditto the plane of section being through the center. Fig. 3, is ahorizontal section of ditto Fig. 2, showing the plane of section.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention relates to a new and improved smoothing or sad iron, thekind provided with a fire chamber or box to contain fuel and which maybe termed self heaters.

The nature of the invention consists in the peculiar arrangement of thepassages which supply the fire with air and the arrangement of the exitor smoke passages, and fluting attachment as will be presently shown anddescribed.

To enable those skilled in t-he art to fully understand and construct myinvention I will proceed to describe it.

A, represents the fire chamber or box, the bottom (a), of which formsthe heated surface which is rubbed over the clothes to be ironed. Thebotto-1n (a), is of the usual form, and the fire chamber or box is madesufficiently high to contain a requisite quantity of fuel, charcoalbeing chiefly used. Wood coals will also answer.

At the front and back ends of the fire chamber or box there is placed avert-ical tube or pipe (Z2), one at each end see Figs. 2,. and 3. Thelower ends of these tubes project inward a. short distance toward thecenter of the tire chamber or box the tubes extend ing downward to thebottom (a). The up per ends of the tubes communicate with the externalair at the upper parts of the front and back ends of the fire chamber orbox as clearly shown in Fig. 2. At each side of the fire chamber or boxA, at its upper part there is made two apertures or holes. Theseapertures or holes serve as exit passages for the smoke and gas fromt-he fuel. The holes at one side of the fire chamber 0r box aredesignated by (c). (0), and at the opposite side one is designated by(c), and the other by (0). To the front side of the fire chamber or boxA, there is a projection B, the

upper surface of which is somewhat rounded. This projection serves as afluting iron. The projection is hollow and its lower part communicateswith the lire chamber or4 box A, by an aperture (d), shown by dottedlines in Fig. 2. The upper part of the interior of the projectioncommunicates with a tube C, the outer end of which terminates at theaperture or hole (0) which is the mouth of the tube O, see Figs. l and3. The apertures or holes (c), and also the aperture or hole (0), andthe mouths or upper ends of the tubes (Z2), (b), are each provided witha cover or register (e), for the purpose of regulating the draft of thefire.

D, is the cover of the fire chamber or box A, which has an upright (f),at each end.

between t-he upper parts of which a handle E, is secured. f

The fuel is placed within the chamber or box A, and ignited, and as theimplement is used, mov-ed back and forth over the clot-hes, the air isforced down the tubes (b), (b), and feeds the flame or supplie-s it withoxygen, the air passing down the tube at the front end of the lirechamber when the implement is shoved forward and down the back tube whenthe implement is moved backward. The smoke and gas escape through theholes (c), (c) and a perfect draft is thereby obtained for the fire.

In case fluting is to be done the apertures or holes (c) at the sides ofthe re chamber or box A, are entirely covered by the covers or registers(e), and t-he heat then passes through the aperture (d), into theprojection B, the smoke and gas escaping through the tube C, and outthrough the aperture or hole (0') as indicated by the black arrows. Thedotted arrows show the air passing into the chamber or box A, and thedotted arrows l show the smoke and gas escaping through the apertures orholes (c).

Vhen it is not required to heat the projection B, the aperture or hole(e) may be covered or not, it is immaterial, but if the projection is tobe heated it is essential that the aperture (0'), be open and theapertures (c), closed in order that the whole draft may be through theprojection B, and insure its being perfectly heated,

The advantages of the above invention are that a perfect draft isobtained for the re within the chamber or box A, for air is forced intothe chamber or box both at the forward and backward movement and thefire is consequently fanned all the time the implement is used and noashes car pass out of the chamber or box because the tubes (b), are in avertical position and do not afford convenient outlets for its escape.In many cases collars are attached to work which require to be iiutedand by the above implement, the fluting may be donc over the projectionB immediately after the other parts of the work are ironed theprojection being in a proper heated state by arranging the registers aspreviously described.

I am aware that self heating smoothing or sad irons have be'enpreviously invented one kind is heated by a lamp another kind is heatedby charcoal, and has a smoke pipe in front, and an opening behind toadmit air to feed the flame. The latter will not be generally used inconsequence of the imperfect draft, for the fire is only supplied withair while the implement is moved backward, and when moved forward theair is forced down the smoke pipe, and the ashes is blown out throughthe opening behind, and the bottom of the iron is imperfectly heated inconsequence of the draft piece admitting the air across the center ofthe bottom of the fire chamber thereby keeping a large surface, agreater portion, of the bottom of the fire chamber cool. This objectiondoes not exist in my improvement, as the air is admitted at the ends ofthe fire chamber or box.

Having thus described my invention what I claim as new and desire tosecure by Let-- ters Patent is,

1. The tubes or pipes (b), (b), placed one at the front and the other atthe back ofthe fire chamber or box A7 and the openings or holes (c), atthe sides of said chamber or box arranged substantially as shown for thepurpose specified.

2. I further claim the hollow projection B, attached to the fire chamberor box A,

and communicating with said chamber or G. W. BISHUP.
